Variable fractal dimension: A major control for floc structure and flocculation kinematics of suspended cohesive sediment

While the fractal dimension of suspended flocs of cohesive sediment is known to vary with the shear rate, electrochemical properties of the sediment and environment, geometrical restructuring, and presence of organic matter, experimental data presented in this work suggest changes in fractal dimension also during floc genesis at constant...

Flocculation Dynamics of cohesive sediment

Cohesive sediment suspended in natural waters is subject not only to transport and deposition processes but also to reactions of flocculation, \textit{i.e.} aggregation of fine particles, and breakup of aggregates. Although aggregation and breakup occur at small and very small length scales compared to transport and deposition, flocculation can...

Survey of the numerical characterisation of 2-D complex clusters

The study of cluster format ion is common in many fields of science and technology (aerosols, colloidal suspensions, hetero-disperse particulate systems in general, growth processes far from equilibrium, etc.). The term "cluster" is a general word indicating an object consisting of a set of elementary unit es organised with a certain structure....
